Patent DE-4115217-A1 (DE)
Inventor: ECKHARDT ULI
IPC: F16H57/021
Filed: 1991-05-10
Abstract: The invention relates to a bearing assembly for a transmission shaft (10), such as, for example, a differential drive shaft with bevel pinion (12) of a vehicle transmission, exposed to bending forces and accepting axial forces. The bearing assembly consists of at least one radial cylindrical roller bearing (18) and two thrust bearings. The inner bearing race (16) of the radial cylindrical roller bearing (18) is supported radially and in an axial direction against the shaft (10). The thrust bearings are arranged on both sides of a bearing housing (40) which can be secured on the transmission case (48) and are supported against the said housing. The thrust bearing which faces the radial cylindrical roller bearing (18) is supported in the said direction against the inner bearing race (16) of the radial cylindrical roller bearing (18). The radial cylindrical roller bearing (18) and the thrust bearings are furthermore fixed against axial displacement on the shaft (10). For a compact design of the bearing assembly which takes up little installation space and contains bearings which are simple to manufacture, it is proposed to use cylindrical roller thrust bearings (22, 24) as thrust bearings and to design the flange-like bearing housing (40) and/or its fixing on the transmission case (48) in such a way that, when the shaft bends, the regions of the bearing housing (40) against which the cylindrical roller thrust bearings (22, 24) are supported adapt to the oblique position of the transmission shaft (10). For this purpose, it is both possible for the bearing housing (40) to be fixed to the transmission case (48) by anti-fatigue bolts (50) yielding to axial forces and for the bearing housing (40) to have areas of varying stiffness in the circumferential direction.

Patent DE-4207914-A1 (DE)
Inventor: HARA KENJI
IPC: G05G9/04
Filed: 1992-03-12
Abstract: The device for remotely controlling a multi-axial device such as a manipulator has an extendable arm 12 mounted on a base 14 by a bracket 16 which provides two perpendicular rotational axes and a handle 22 which is mounted on the arm 12 by a bracket 24 which also provides two such axes. In a modification (Fig. 4) the handle is capable of three axes of rotation. including roll, which may be arranged to coincide with the operator's wrist joint (Fig. 5). The arm portion thus outputs operational changes with respect to three axes of the horizontal rotation, the vertical rotation and the extending movement. The arm front portion outputs operational changes with respect to the three axes of the horizontal, vertical and rolling rotations. Thus, the number of axes employed in the master can be increased to detect a variety of movements thereof. The operational directions of the joystick agree with the directions of the three rectangular coorindate axes. Thus, the device provides three-dimensional data regarding position and angle. <IMAGE>
Patent DE-4212407-A1 (DE)
Inventor: BAUMGARTNER HANS
IPC: F16D66/02
Filed: 1992-04-13
Abstract: The invention relates to a clearance detector for a pneumatically operated disc brake having a brake caliper (2) surrounding a brake disc (1) on one side of which is arranged a brake application device (3) which, via at least one adjusting spindle (72, 73) and a pressure member (70, 71) fitted to its end nearest the brake disc, acts on a brake pad (10) fitted in the pressure side of the brake caliper (2) so as to move in relation to the brake disc (1). An adjuster (74) coupled integrally in rotation with the adjusting spindle (72, 73) keeps the clearance, which changes as the brake pad wears, substantially constant and is coupled to an angle of rotation sensor (54), the output signal (A) from which corresponds to the current degree of brake pad wear. In order to detect the current air clearance there is an evaluation device which detects the value of the output signal (A) from the angle of rotation sensor (54), calculates the signal difference (D1, D2, D3) from the previous signal value at any change in the output signal (A) and determines the current clearance from said signal difference (D1, D2, D3).

Title: Variable servo steering method with mechanical servo drive - using two fixed friction clutches and one adjustable friction clutch, variable with steering lock
Inventor: SPENGLER EBERHARD DIPL ING
IPC: B62D5/04
Filed: 1992-06-13
Abstract: The method involves using a mechanical drive with a gear wheel (32) which drives two floating, parallel gear rings (30) which couple to the steering via friction clutches. One of the clutches (18) is movable to alter the friction effect and thereby the servo effect as well as the reaction force which the driver experiences. The servo effect can also be adjustable via other mechanical parameters. The angle of grip of the gearing can be adjusted, or the alignment of the friction clutches. This provides a servo effect variable with steering lock. ADVANTAGE - Simple to adjust servo steering effect, control of self centering effect of steering improving straight ahead driving characteristics.
